Cannot connect to remote network through OpenVPN instance with client overrides

Hello,
I'm a novice Systems Admin for an Eye Clinic in rural Kansas. We have two locations connected through an IPSec tunnel. Currently I have an OpenVPN instance configured to access the local network of Site A. This functionality is working fine. However, I need the VPN to allow access to both sites and adding Site B as a remote network appears to not change the routing tables of connected clients. I have a client override that also specifies the remote network, and have tried all combinations of server/client override specified remote networks as suggested in other forum posts. I'm at a loss for what to do next. Below I have documented my configuration for the server, client overrides and firewall rules. I'm hoping that someone can spot the issue or suggest an easier alternative to solve the issues. I'm fairly new to all of this and sometimes can be a bit short sided on alternative solutions.
If there is any other information I can provide you with, I'd be happy to ASAP.
Thanks,
Brady
